She said: “I put [the sign] there because of the way people treat me in Ossett.

“They just open the door of my cafe and once they take a look at me they walk out.”

The sign put up at the Yeanon Cafe

The single mother-of-three has run the cafe for two years, serving freshly prepared British, Afro-Caribbean and Southern American specialities like pulled pork, oxtail and goat curries.

Many people have posted messages of support on the cafe's Facebook wall. One said: "It's disgusting and upsetting that you and your customers should have to waste a moment of your life, even thinking about posting a notice that you want to be free to live your life. I am white British and am no better than you or any other black person."

Another wrote: "Good luck with your cafe! It's so sad that you needed to put a sign on your door because of the bigots and idiots in this world. I wish you every success."
